I purchased a 2006 CPO a few weeks ago and found the squeek to be quite strange. Not even my 98 Civic squeeks that much. I took it to 2 different dealerships in the area to resolve, but none could properly fix.

They claimed to have cleaned some adhesive on the seal, but the squeak would come back after a rainy day or after a few days of leaving the dealer.

It was only until the 3rd visit (yes 3X) I took it back that they replaced the door seals on the drivers side -- thankfully this did fix the issue. However my right side was acting up... With frustration at an all-time high, I read this thread and tried what 328idogg recommended (terrific screenshots), and yes he was right.

Turtle Hard Wax liquid and Vinylex works like a charm. Vinylex I found @ PepBoys, and the process takes less than 10 minutes to do.

I have had this problem on both my E46 320D & my new E90 320D. The reason I bought the E90 was due to the fact that Scotthall BMW couldnt rectify the 'rattly door' issue even with the Teflon tape that just snarled itself up and made a right mess. Within the first few days of being the 'proud' owner of an E90, the car was returned for the very same fault. I havent had time to take the car back for 18 months but with it beginning to sound like a 20 year old taxi, and getting absolutely no driving pleasure from it, I searched the internet and found that I was not the only one with an rattly car. I found that putting a PTFE lubricant on the seals quietened the doors down by around 90%, the other issues were rattly dash, rattly parcel shelf, rattly centre console (under the air con controls) and rattly A pillars. (Not been lucky have I?) Scotthall BMW had the car in a few weeks ago when I finally managed to get some time off and cleaned and 'resat' the seals but three weeks later they are beginning to creak/moan again. I have booked the car in again and given Scotthall an ultimatum that they should provide a permanant repair or take the car back. Its only just gone 2! Has anyone had any real joy (forgive the pun) at getting this problem fixed without having to resort to applying lubricants to the seals?

I have a 2009 328i sedan w/sports package that has squeaky door seals when going over bumps or when the body flexes.

This is more apparent on the rear doors and the driver's door. At highway speeds (even on bumpy highways), it's completely silent, as if air pressure is keeping the door seals from shifting/rubbing. Before I take it to the dealer, I was just curious if anyone else has come across this?

It appears to be the door seals rubbing against the black shadowline trim. I'm not sure if this would happen on cars with chrome trim. I can completely eliminate it by placing blue painter's tape on the door seals where it contacts the trim. Another way to temporarily quieten it is by applying something like Meguiar's NXT Protectant to the rubber seals, but it returns after a few days. Note that this is just on the upper-most rubber seal, which touches the trim, not the main seal which goes all the way around the door and contacts the metal body frame.

I've searched the SIBs, but the closest fixes are for X3's and 5 Series (links below). You would have thought BMW would have completely gotten rid of those poor seals.

I own a 2010 335d and am currently experiencing the same problem. I have a US Spec'd car and live in Germany. I just received my car from the BMW dealer and they told me they had to open an inquiry with BMW because after lubricating and then replacing all the door seals, the car still makes noise. They told me the US cars and EU cars have different part numbers for the seals. They believe BMW will tell them to use the EU seals as a fix, but they are not authorized to do so until Munich allows them. I will follow up once I know more and my problem is fixed.

OT... This 335d is by far the best overall well rounded daily driver I have ever owned. What a car!

The Shadowline trim is the black trim around the frame of the door opening on the car body. Note that some models have chrome trim. Apply RejeX/wax to this part.

On the door side, there are 3 areas (shown in the arrows). I just applied Vinylex to the door seal shown with red arrows. That's the part that actually contacts the Shadowline trim and causes the squeaks. You don't have to apply anything to the felt flocking or the larger main rubber door seal.

Hope that helps.

This is a very helpful thread. I started noticing this squeaking / creaking a couple days after picking up a CPO 2009 328 with sport pkg. Issue was just as others have described. I read these posts then applied Vynelex to both the door seals and the underside of the shadowline trim. It worked completely. I'm expecting it may wear off in a few days, but my local auto parts store didn't have the wax described for the trim, and I was reluctant to experiment too much. Anyway, the fact that the Vynelex worked shows the nature of the problem and points to a more durable solution. Thanks. All!

Well mine has been squeaking a while in the drivers side and I was told it may be a suspension bush. After reading this I'm wondering if it's the door seal anyone know how much BMW charge for a new in UK ?

An update: About two weeks into the experiment, my Vinylex treatment still seemed to have cured the creaking at the door seals. But since I doubted its longevity, and based on the experiences of an earlier poster, I decided to wax the (presumably) offending Shadowline trim. I used Mother's California Gold Pure Carnuba Wax, figuring it was both high quality and less likely than other waxes to be bad for the plastic trim.

A few days since applying it to the Shadowline, a bit of creak has returned, if intermittently. I don't report this to discourage people from trying to wax the tim (there could be several reasons for my experience), but rather to affirm the (at least short term) value of just using Vinylex on both the door seal and the trim. That worked on its own for at least a couple weeks. And I note it is available in disposable wipe form, making it pretty convenient to use and keep on hand...

I took my 2010 335i into the dealership when I only had 1,500 miles on it and they told me it was the 3rd party window tinting causing the noise. They lubed the seals in the meantime and the noise disappeared for a couple of hours. Then, I took my car to another dealer for the first maintenance warranty and noted the noised. Not sure what they lubed the seals with but the noise has been gone a week so far. SO NICE! The Service Coordinator admitted it is a known issue and if the noise comes back, they will have the seals replaced. I asked them for the name of what they use but he did not know. Anyway, I;ll look into some Wurth and the other products mentioned. Wish I went to that dealer about 13k miles ago

The title of this thread should be revised, possibly made a sticky... as it apparently applies to all E90 E92, all years, possibly all models!

I have 14,000 miles on a 2011 335D sport pkg, shadowline.
All four doors creak like a concert, 24-7.
My car is garage kept for weeks at a time. Maybe it sits outside a night or two while traveling. Neither make a difference to the concert I'm hearing.

-> I hand wash my car once a week. Then spray wax it. I'm curious if those who have the major squeaking (from all doors) are those who are washing as often as I. (although I do imagine some here detail every other day!

I haven't tried anything yet. But all of my clients, friends (enthusiasts or not), everyone says, wow this car is amazing, but the creaking sounds are terrible, wtf.

My seals don't appear to be dried up or damaged. They seem to be in excellent condition.
The noises I'm hearing are constant and all speeds, even on smooth even highways, driving straight away, at cruising speed.

Thank you to everyone who has suggested fixes and keep us updated.
Thank you 328idogg for the pics or where exactly to apply!

However...

...this appears to be the safest method to treat the seals. some of the suggestions could have adverse effects.

Same here!

One person, in this thread or another, mentioned he lubbed the door hinges and it helped. Anyone else care to comment on this?

I use a product DOW CORNING 111. valve lubricant and sealant - on rubber seals for my convertible/hard top/soft top jeep wrangler. the hard top seals (similar to a targa) are terrible and dry out. this product works well and shares the main ingredient as the gummi product , polydimethylsiloxane, great word4friends word eh?

di-electric grease silenced my rear right seal for almost 8 month. It is a lot more efficient that regular seal grease, but is not dry and lets residues everywhere. Really to be used on the exact area that's causing noise problem. For the rest I use gummy pfledge, so far it has kept my seals supple without putting grease all around the place so I am happy. Got it on the cheap from amazon.
